Can ‘toxic’ bilirubin treat a variety of illnesses?
Generations of medical and biology students have been instilled with a dim view of bilirubin. Spawned when the body trashes old red blood cells, the molecule is harmful refuse and a sign of illness. High blood levels cause jaundice, which turns the eyes and skin yellow and can signal liver trouble. Newborns can’t process the compound, and although high levels normally subside, a persistent surplus can cause brain damage.
Yet later this year up to 40 healthy Australian volunteers may begin receiving infusions of the supposedly good-for-nothing molecule. They will be participating in a phase 1 safety trial, sponsored ...

When does life end? New organ donation strategy fuels debate
On a chilly holiday Monday in January 2020, a medical milestone passed largely unnoticed. In a New York City operating room, surgeons gently removed the heart from a 43-year-old man who had died and shuttled it steps away to a patient in desperate need of a new one.
More than 3500 people in the United States receive a new heart each year. But this case was different—the first of its kind in the country. “It took us 6 months to prepare,” says Nader Moazami, surgical head of heart transplantation at New York University (NYU) Langone Health, where the operation took place. The run-up included oversight from an ethi...

The final puff: Can New Zealand quit smoking for good?
Smoking kills. Ayesha Verrall has seen it up close. As a young resident physician in New Zealand’s public hospitals in the 2000s, Verrall watched smokers come into the emergency ward every night, struggling to breathe with their damaged lungs. Later, as an infectious disease specialist, she saw how smoking exacerbated illness in individuals diagnosed with tuberculosis and HIV/AIDS. She would tell them: “The best thing you can do to promote your health, other than take the pills, is to quit smoking.”
Verrall is still urging citizens to give up cigarettes—no longer just one by one, but by the thousands. As New...

How to Keep Alzheimer ’s From Bringing About the Zombie Apocalypse
I tried to kill my father for years. To be fair, I was following his wishes. He’d made it clear that when he no longer recognized me, when he could no longer talk, when the nurses started treating him like a toddler, he didn’t want to live any longer.
My father was 58 years old when he was diagnosed with Alzheimer’s disease. He took the diagnosis with the self-deprecating humor he’d spent a lifetime cultivating, constantly cracking jokes about how he would one day turn into a zombie, a walking corpse. We had a good 10 years with him after the diagnosis. Eventually, his jokes came true.
Seven years ...

The robot suit providing hope of a walking cure
Clothing that can help people learn how to walk again after a stroke is the brainchild of a Harvard team reinventing the way we use robot technologyConor Walsh ’s laboratory at Harvard University is not your everyday research centre. There are no bench-top centrifuges, no fume cupboards for removing noxious gases, no beakers or crucibles, no racks of test tubes and only a handful laptop computers. Instead, the place is dominated by clothing.On one side of the lab stands a group of mannequins dressed in T-shirts and black running trousers. Behind them, there are racks of sweatshirts and running shoes. On another wall of s...

The Bonus Effect: One Kind of Interest That Rewards DON'T Kill
For nearly half a century, research has raised troubling questions about the practice of dangling rewards in front of people to get them to do what we want. It doesn't matter whether the people in question are male or female, children or adults. It doesn't matter whether the rewards are stickers, food, grades, or money. It doesn't matter whether the goal is to get them to work harder, learn better, act nicely, or lose weight. What the studies keep telling us is that rewards, like punishments, tend not only to be ineffective -- particularly over the long haul -- but often to undermine the very thing we're trying to promote....

A Surprising Number Of People Can't Recognize Voices
For me, caller ID is one of the best inventions of all time. Before it became mainstream, I dreaded picking up the phone. A lot of times, I couldn’t recognize the person on the other side by just hearing his or her voice, and so I was often subjected to a slew of jokes and mockery and puzzle-solving.
It turns out I was hardly alone in my misery. An inability to identify people by their voices is a poorly understood deficit called phonagnosia ― a term coming from “phone,” meaning “voice” in Ancient Greek, and “agnosia,” meaning a “loss of knowledge.”
And the ...

If you can't imagine things, how can you learn?
We know some people can’t conjure up mental images. But we’re only beginning to understand the impact this “aphantasia” might have on their educationNever underestimate the power of visualisation. It may sound like a self-help mantra, but a growing body of evidence shows that mental imagery can accelerate learning and improve performance of all sorts of skills. For athletes and musicians, “going through the motions,” or mentally rehearsing the movements in the mind, is just as effective as physical training, and motor imagery can also help stroke patients regain function of their paralysed limbs.For most of us,...

Does the Brain Filter out a Wider Awareness?
The human brain has amazing capacities. It contains billions of neurons, allowing it to process vast quantities of information so that we can function effectively. But can we have too much information? Yes, and, in fact, filtering information is one of the brain's most important functions. Brain filtering is an adaptive strategy and ensures that only the information relevant to our goals is allowed into our consciousness. This keeps us from being flooded with irrelevancies that might distract us.
To introduce brain filtering to my neuroscience students, I show them a video of two teams throwing a ball back and forth, and ...

White Doctors In Training Believe Some Disturbing Stuff About Black Patients
When it comes to emergency care, you may have a tough time if you're in pain and not a white man. Previous research has shown that black and Hispanic patients who reported severe pain in the the ER were 22 percent less likely to receive pain medication than white patients who presented with the same complaints. And women suffer similar disparities: A 2008 study found that women wait an average of 16 minutes longer to receive pain relief for acute abdominal pain in the ER than men do. Now a new study is shedding some light on this phenomenon. "We’ve been looking at racial bias and pain perception to tr...

What Your Tongue And Tonsils Could Tell You About Your Sleeping Habits
Your dentist might be able to tell if you're having trouble sleeping. Yes. A new study published in the Saudi Medical Journal found that the size of a person's tonsils may indicate their risk for obstructive sleep apnea, a condition in which blocked upper airways cause breathing to stop and restart repeatedly during sleep. Tongue indentations, or teeth imprints on the tongue that suggest it's too big for the mouth, may also be a sign. More than 18 million adults in the United States are affected by OSA. Since people with the condition are often suffering from interrupted and reduced sleep, it can lead to ...

Glyn Humphreys obituary
Key figure in cognitive neuroscience whose research helped many stroke victimsWhen the neuropsychologist Glyn Humphreys, who has died suddenly aged 61, took up his first lectureship, at Birkbeck College, London, a student with a background in physiotherapy joined his class. She asked about the implications of David Marr’s theory of visual perception for the understanding of patients who experience visual disturbances after suffering a stroke. This led to a lively discussion and a subsequent visit to a stroke clinic. It proved to be a turning point in Glyn’s research, highlighting the many ways in which brain damage can...

Can You Think Yourself Into A Different Person?
For years she had tried to be the perfect wife and mother but now, divorced, with two sons, having gone through another break-up and in despair about her future, she felt as if she’d failed at it all, and she was tired of it. On 6 June 2007 Debbie Hampton, of Greensboro, North Carolina, took an overdose of more than 90 pills – a combination of ten different prescription drugs, some of which she’d stolen from a neighbor’s bedside cabinet. That afternoon, she’d written a note on her computer: “I’ve screwed up this life so bad that there is no place here for me and nothing I can contr...
